TRANSOM-LFTER.

Application filed August 17, 1916.

it known that 1, lViLLiAi-r l?. ORoniirin, a citizen ot the lUnited States, and a i.esi. 1lent of Chicago, count)7 ot Cook, and lt'ltate of illinois, have invented certain new and useful lmpror-.f'ements in Transom-Litters, of which the following is declared to be a full, clear, and exact description.

rllhis invention relates to transom litters, and its primary object is to provide a simple, etlicient and practical device tor adjusting transom windows or other hinged window sash. rThis invention relates in particular to t 'ansom litters ot that type which employ a stationarilv supported rod adiacent the transom window, a rod clamp slidablj,Y mounted thereon and having rod gripping levers pivotally supported in the housing ot the rod clamp, and an operating` rod engaging said rod gripping levers and eX- tending down to within reach ot the operator. One of the objects ot this invention is to provide a transom litter ot this type, capable ot use either on the right or lett hand side of a transom window. Another object is to provide a rod clamp in which the rod gripping levers are entirely concealed trom view and wholly contained within the housing so as to be less likely ot iniurv from external sources. lVith these and other objects and advantages in view, this invention consists in the several novel features hereinatter 'fully set Yforth and claimed.

rllhe invention is clearly illustrated in the 'drawing accompanying this specification, in

which:

Figure 1, is a 'front elevation of a simple form oi my present invention applied to a door trame and transom window; Fig. 2, is a side elevation thereof. looking in the direction ot the arr Q in Fig. 1 g is a central vertical section taken on the line 3-3 of' Fig. 1; 1l, is a horizontal section taken on the line t-ll ot Fig. 3. and Fig. 5, is a rear view ot' the rod clamp.

Referring to said drawing, the reterence numeral 6. designates a door casing. 'to which is hinged a door 7, above which is the usual transom 8, having the transom winden'v 9, hinged to it by hinges. one ot which is seen at 10. Stationaril;T mounted upon said casing is a verticall7 extending rod 11. which as shown may be secured to the casing G, by brackets 12. fastened upon the ends ot the rod and screwed to the cas- ISlidaloly mounted upon said station- Specication or Letters Patent.

arily supported rod 11, is a rod clamp 13, which comprises a housing 111, preferably rectangular in shape and having a trent wall 15, side walls 16, and end Walls 17, the rear of the housing being open. rllhe end Walls 17, oit said housing are formed with alined openings 18, tor the reception of the stationarily supported rod 11, as is clearly indicated in Fig. 3.

Lugs 19, 19a, are termed upon the inner tace of the side walls 16, and are arranged in pairs as seen in 5, there being tour pairs of lugs oi. which the lugs 19. are short ones. whereas the lugs 19t, are long lugs. lle/tween the opposing pairs ot lugs aro placed angular-ly disposed, rearwardlj,7 eX- tending rod gripping' levers 520, 21, each ot' which formed with two holes near its tree end. and the stationarili7 supported rod 11 passes through the two alined holes nearest the ulcriun; between said gripping levers coiled compression spring which surrounds the rod 11, and bears against the rod gripilimg levers. Said levers are pivotallj,T

supported between the opposing pairs ot lugs and niav rock therebetween, the long` lugs 19%, f* ving to limit the movement ot the rod gripping levers toward one another, and the oppositelj.7 disposed lugs 19, serving to limit the movement ot said levers in they opposite direction. .'n operating rod y, afviug a suitable handle oi' other grip bl, upon its lower end is slidablv mounted in the lower rod supporting bracket 12, and extends through the outer alined holes in the rod gripping levers 20, Q1. there beine' shoulders on said operating rod adapted to engage with the outer sides ot aid levers. For conreuience. the rod is reduced in diameter. at the place where passes through said levers, to form a shoulder 24,-?. and the other shoulder is 'formed by a washer 'which is secured uiii'on the extreme end et the rod. The end walls 17. o? the housing are notched out to receive the 'rod is clearlv indicated in 3, andy l, whereby7 the levers may be wholly contained in the housing. The rod clamp housing is connected to the transom window bv a brace rod 2G. and an angular transom bracket 27, and in order to make the transom litter usable either on the right or lett hand side of the transom window. I pivot the brace rod 2G, to the middle ot the front wall 15, of the rod clamp housing b v providing two ears :28, on said trent wall, which ears are spaced apart to receive a fitting 28a, that is secured upon the upper end of the brace rod. Said brace rod lies in the same plane as the stationarily supported rod 11, and operating rod 23, and is secured to the transom bracket 27, by a coupling 29, which is threaded upon the end of the brace rod 26, and is rotatively connected to the end of the angular transom bracket 27, whereby an adjustment is afforded to permit the angular transom bracket to be placed on either side of the brace rod. Said transom bracket 27, has the usual base 30, which is screwed to the transom window.

The operation of this device is readily apparent from the above description. Movement of the operating rod in either direction first swings the rod gripping`- lever (against which it pushes) until said lever strikes an adjacent .long lug 19, which limits its movement relative to the housing, and the continued movement of the operating rod 23, thereupon moves the clamp rod housing with it, thus moving the brace rod and transom bracket 27, and opening or closing the transom window, depending upon which direction the operating rod is moved.

It is to be observed that the rod gripping levers are Wholly inclosed in the housing so that they are not liable to become disarranged or interfered With from outside sources. Furthermore, by reason of the centrally located pivot connection between the brace rod and rod clamp housing and the adjustable connection between the brac-e rod and transom bracket, the transom lifter is made usable on the right or left hand side of the transom window. Furthermore, by running the operating rod through the end holes in the rearwardly extending gripping levers, the operating rod may lie close to the door casing.

More or less variation of the exact details of construction shown and described is possible `without departing from the spirit oi' this invention, and I desire, therefore, not to limit myself to the particular form of the invention shown and described, but intend in the following claims to point out all o'l' the invention disclosed herein.

I claim as new and desire to secure by Letters Patent:

1. A transom lifter, comprising a stationarily supported rod, a rod clamp housing closed at the front and Jformed with spaced lugs on its interior, said housing being slidably mounted thereon, angularly disposed, rearwardly extending rod gripping levers pivotally supported between said lugs in said housing, each having two holes ini its :tree end in alinement with corresponding holes in the other lever, and said rod passing through one pair of alined holes, a coiled compression spring encircling said rod and extending from one of said levers to the other, an operating rod extending through the other alined holes of said levers and having shoulders engaging the outer sides of said levers, a brace rod pivotally connected to a lug formed on the front wall of said housing and lying in the same plane as the stationarily supported rod and operating rod, and an angular transom bracket adjustably secured to said brace rod and adapted to be secured to a transom window, at either side of said rods.

2. A transom lifter, comprising a stationarily supported rod, a rod clamp housing slidably mounted thereon, said housing having a front wall, sides and ends and open at the back, and having four pairs of spaced, rearwardly extending, oppositely disposed lugs cast upon the inner sides of the side walls, two angularly disposed, rearwardly extending rod gripping levers, each pivotally supported between two pairs of oppositely disposed lugs, and each lever having two holes in its free end in alinement with corresponding holes in the other lever, said rod passing through two alined holes of said levers, a spring extending between said levers, an operating rod extending through the other alined holes of the levers and having shoulders engaging the outer sides of said levers, a brace rod pivotally connected with ears extending out from the front wall of said housing, said brace rod lying in the same plane as the stationarily supported rod and operating rod, and an angular transom bracket adjustably secured to said brace rod and adapted to be secured to a transom window at either side of said rods.
